Parameter setting procedure for dancer
control function
Continued from the last page.
Line speed
input
calibration
Input method for line speed
Analog input
When
Pr. 763
= "3,
4, 5 or 6"
Pulse train input
When
Pr. 763
= "1, 2 or 7"
Without line
speed input signal
When
Pr. 763
= "0"
For
Pr. 765 Voltage reference for line
speed input
, set an analog voltage
which is input to the inverter when the
line speed reaches the set speed in
Pr. 766
.
(Refer to page 33)
For
Pr. 764 Pulse reference for line speed
input
, set a pulse frequency which is
input when the line speed reaches the
set speed in
Pr. 766
.
(Refer to page 33)
Calibrate the line speed for the line
input signal according to the input
method of the line speed.
Set a reference value for the line feeding speed in
Pr. 766
Line speed reference
.
(Refer to page 33 )
Enter the same setting unit as
Pr. 766
in
Pr. 767 Line speed
unit
.
(Refer to page 33 )
Winding
diameter
compensation
setting
Set winding diameters.
Pr. 720 Maximum winding diameter 1
=
"Maximum diameter"
Pr. 721 Minimum winding diameter 1
=
"Minimum diameter"
(Refer to page 35)
Set a sampling time for the winding
diameter calculation.
Pr. 707 Sampling time for winding
diameter calculation
= "0.01 to 1s"
Pr. 786 Number of averaging for winding
diameter calculation
= "4"
(Refer to page 38)
Extend the sampling time and
increase the averaging count to
reduce fluctuation of winding diameter
compensation.
Set the maximum magnitude of value
obtained from winding diameter
calculation per sampling.
Set
Pr. 771 r-r' limit value (diameter)
according to the material rolled up.
(Refer to page 38)
Test run
REMARKS
If winding diameter compensation does not operate at low-speed operation, check the setting of
Pr. 797 Rotation speed at winding diameter
calculated value activation
(initial value is 3Hz).
